S401M-C25NP ABB MCB 2CCS571103R8254 2P, 25A Curve C, 415V AC

The S401M-C25NP is an ABB Miniature Circuit Breaker (MCB) with the following key specifications:

1. Model: S401M-C25NP
2. Type: 2P (Two Pole)
   • It means the breaker is designed to protect a two-phase circuit.
3. Rated Current: 25A
   • The MCB is designed to carry up to 25 amperes of continuous current without tripping.
4. Breaking Capacity: Typically, the S401 series can handle high fault currents, with a typical breaking capacity of 6 kA (at 415V AC, depending on the specific variant). This makes it suitable for a range of industrial and commercial applications.
5. Trip Curve: Curve C
   • The C curve indicates that the breaker will trip when the current reaches 5-10 times the rated current. It’s designed for circuits with moderate inrush currents, such as those with motors or transformers.
6. Voltage Rating: 415V AC
   • This is the maximum voltage the MCB can handle. The breaker is suitable for standard industrial and commercial AC circuits (typically used in 3-phase, 415V AC systems).
7. Poles: 2P (Two Pole)
   • It protects two conductors (typically live and neutral in a 2-phase system).
8. Series: S401M
   • The S401M series is designed for general industrial, residential, and commercial applications. It offers reliable overcurrent protection, preventing damage from short circuits and overloads.
9. Application:
   • This MCB is typically used in industrial environments, buildings, and installations where protection against short circuits and overloads is essential for two-phase electrical circuits.
10. Part Number: 2CCS571103R8254
    • This is the specific part number associated with this model for ordering and reference.

Key Features:

• Compact size for space-saving in electrical panels.
• Thermal-magnetic protection, providing both overload and short-circuit protection.
• Reliable performance in a wide range of applications.
• DIN Rail mountable for ease of installation in distribution boards.

Applications:

• Industrial machinery and equipment.
• Commercial buildings (e.g., office buildings, factories).
• Residential electrical installations (for specific use cases).

This MCB is designed for use in environments where reliable circuit protection is required, ensuring that electrical installations are safeguarded from both overload and short-circuit conditions.
